Loading values from the PxWebQuery component via the while cycle

If you want to load some values for all rows in the PxWebQuery component,
you can do it via the while cycle.
This way of working with the PxWebQuery component is very similar to working
with the TTable components in Delphi programming language. There are two possible
ways of loading data. The first way is to download from the first line to the last.
The second method of loading is from the last line to the first line.
Further here there is an extract of the code where the values are loaded
from the first to the last row and the result is then assigned to the Label component.

The wquAdresar.Eof () command returns true value if the Next () command
cannot move us to the next following row. Similarly, the wquAdresar.Bof ()command
returns the true value if the Prior () command cannot move us to the previous row ,
because we are already on the first row.

Here is a functional example of the PxWebQuery component, even with source code.
This functional example on this site runs on MySQL 5.0 database.

It doesn't the intention of this part website, describe in detail the work with PxFramework components, a detailed description of the component
available in manual, which can be downloaded here: Download manual of Px Framework
